How do I clean the interior of my LifeProof case?

Keeping the inside of your LifeProof case clean ensures that there's nothing between you and your screen which could distract you or keep you from doing
what you want to do with your phone.

To clean the inside of the case, open the case and remove the iPhone. The best way to clean the interior of the case is with a soft cloth, with warm fresh water and a mild detergent. Once you're done,
make sure you rinse it well to get rid of any excess detergent that may remain in the case. Once you've rinsed the case, shake the excess water off and dry
it gently with a clean, soft cloth. If the touch screen area on the inside of the case needs some more attention, wipe it gently with an eyeglass-safe
microfiber cloth.

Tap the O-ring out of the case and check to make sure that it's not damaged in any way. Then, wash it with mild detergent and warm fresh running water and
shake to dry. Once the O-ring is dry, align the top corners and then press the remainders in until you reach the bottom and the O-ring is back in place.
Never use silicone lubricants, as these might allow water to enter the case.
